Yea, I've done it quite a few times. Just like everyone already mentioned, don't weld a front set. Not only will turning be a bitch, but the axleshafts and u-joints are too weak. Is that reareand a regular 14-Bolt, or a Corporate 14-Bolt? Detroit Lockers are great, but still make steering a bitch, when in 4wd. The best thing that I ever bought, was an ARB air locker. You just push the button, and it's locked, just like a welded set of spiders. Push it again, and it's a completely open differential. I absolutely loved mine, and it survived through some brutal off-roading.
I'm sure you already know this, but just in case anyone else is interested. The regular 14-Bolt rearends are 9.5", and the axleshaft is held in by a C-clip, and the Corporate 14-Bolt is 10.5" and the axleshafts are held in by the 8 bolt hubs.
